The NEO Personality Inventory Revised (NEO-PIR) is a tool widely used in psychology to assess people's personality traits. Developed by Paul T. Costa and Robert R. McCrae, the NEO-PIR is based on the Five Factor Model of personality, also known as the "Big Five". This model maintains that personality can be described in terms of five main dimensions: openness to experience, conscientiousness, extraversion, agreeableness, and emotional stability.
Origin and Development of the NEO-PIR
The NEO-PIR is the evolution of the NEO-PI, a previous version of the inventory that was widely accepted in the scientific community.

The NEO-PIR consists of a questionnaire that evaluates the five personality factors and their respective facets, providing a detailed view of the personality structure of an individual.
